I use the g4u disk cloning tool for chores like this. Forget the 80 Gb
spare drive. It is too small for what should be done. Instead get a new
I make sure I have a spare disk of the same type, physical dimensions
and capacity as the source disk and I use the g4u software to clone from
the source drive to the spare. This is usually means putting the spare
drive in an external drive enclosure which I know can be a chore.
When the cloning operation is done, I remove the source disk from the
machine of interest and replace it with the spare disk. This lets me
ensure that Windows XP boots. From then on all disk operations are done
on this disk. The steps I follow are:
* Defragment the NTFS partition
* Download the very latest gparted live cd and boot to it
* Resize the ntfs partition with gparted. It is quite reliable.
* Boot the resized NTFS partition. Windows XP will probably start chkdsk
at boot time, and that can take a little while, but all should be well.
Once you are sure you can boot into XP, shut down the computer and
install Fedora with the unallocated free space.
If something terrible happens...no problem! You still have the original
disk. You can re-clone as needed.
